variable fresnel mirror optics have entered the chat (i made that up, but fresnel mirrors exist and and maybe one could use a 300mm DLP micro mirror device and somehow improve it in a way that the mirrors can be angled in variety of angles instead of just 2, mirrors also have no chromatic aberration)

edit: holy shit the idea isnt even new https://www.nature.com/articles/s41377-020-00420-6
